Tall lwhom it may concern Be it known that I, CLYDE S. PELToN, a citizen of the United States, residing at lleveland Heights, in the county of Cuyahoga and Stat/e of Ohio, have invented a certain new 4Aand luseful Improvement in Heaters for Motor-Propelled Vehicles, of which thefollowing isa full, clear, and exact description, reference being had to the accompanying drawings.

This invention 'relates to vehicle heaters, and especially to heaters for motor propelled vehicles, wherein the hot exhaust gases from the engine are employed to heat the passenger, compartment. invention .are the provision of a device of this character which can be connected to the twin exhaust pipes employed in certain kinds ofniotors, so as to heat the car without at the Sametime throwing the motor out of balance; the provision of a device of this character of great simplicity, eiiiciency and reliability; while further objects and advantages will become apparent as the description proceeds. l t

,In the dra-wine accompanying and forming apart of this application I have illustrated one t construction iny which my said invention may be embodied, although it will Ibe understood that the same is only one of many which could be employed for l lthe purposes in view. In these drawings Figure' 1 represents a perspective view o the heater as seen from the car interior; F ig. 2 is a perspective view of a portion of said heater with the casing removed and certain of the partsI separated from each otlier;l `ig. 3 is a transverse sectional view of said heater; Fig. 4 is a longitudinal vertical sectional view of the same; and

Fig. 5 is a diagrammatic view showing the engine, muiers, and heater; and Fig. 6 is a view showing the same radiator employed witlaV single exhaust pipe,

In some makes of automobiles, engines are employed having two independent exhaust pipes, one on each side of the car, and two independent muiers. In order to secure even operation of the engine itis desirable that these pipes be of the same size and have the same number of bends and be connected to muiilers of the same size and construction; and itis found that if a portion of the exhaust gases of one The objects of the pipe bediverted tov o er'ate a heater the engine is sli` htly un alanced, n added to which is the act that rthe cylinders'are so small and the gas consiimption so complete that the heat derived Afrom a single pi e is frequently inadequate for warming t e vehicle. In order to overcomei these disadvantages I provide "a heater having two inlets, each of which isY adapted to be connected to one of the exhaust pipes, the 'two halves of the heater being exactly the same so that the effect upon 'the two exhaust pipes is identical; and I also'provide two similar valves, one for each exhaust pipe, and means for operating' said valves simultaneously.

I-n these4 drawings, 1 represents thev floor of anautomobile, and 2 and 3 represent the twin exhaust pi es leading from a twin type engine 4. ecured upon these exhaust pipes are similar valves, 5 and 6, respectively, of the usual or any suitable type, the

.so as to facilitate installation.A A sin le lever 11 is provided at some suitable pointV whereby both rock-shafts may, be-'nioved together. y In its preferred form the heater itself comprises twosets of parallel imperforate pipes 25 whose sizes, len hs and numbers are equal so that they will have equal resistanceto gas flow.- Headers are secured tolthe ends of the sets of pipes, said headers being hollow and formed with an inlet chamber and an outlet chamber for each set. In the present embodiment, the inlet chambers are in the fittings 12 and 13, and both outlet chambers f are formed in' the fitting 14, althoughdifferent arrangements can'be employed aswill be obvious. Each of the inlet Chambershas an inlet nipple here shown at 15 which projects beneath the Hoor of the car and is connected to one of the exhaust pipes while the outlet chamber also has discharge means such as the nipple 18 projecting downwardly and discharging below the car floor. These nipples are here shown as provided with flanges 16 and 19 respectively whereby the 'heater is supported, and a suitable casing incloses all Ioriv are v-.preferably curved downwardlyrv toward the nipplel 18, as illustrated at f30, 30, so as to deflect toward said nipple the hot gases,

yerably provide the .nipple 18 with tube-securing provisions; such as an aperture, 35,

for the reception of a set screw,'so that an outlet pipe can be attached thereto if` desired to convey the exhaust to any particu l lar point before discharging the sameyand, likewise, this-permits me, as I have. sometimes done,`to employ vthisfheater with an engine having only: a single exhaust pipe 40 and 'houiller 41, connecting this exhaust pipe to the nipple 1 8, and Aallowing thegases,- td escape through both the, nipples 15, 15, as shown in'lig'l`v`` f i 5A heater made and connected in this manner oiers certain marked advantages in connection with a single exhaust pipe over heat# ers of a simpler type, 4in thatthe internal resistance is smaller owing to the r freeoutlet afforded vby two 'distinct paths, which produces an extremely rapid flow of gas.' It will be understood that the only force tendw ing to expelthe gases through' the heater -'resides in the back pressure created by the niuiiier, 41,v since it is not permissible; to close off the maln outlet at time since this would impede `the engine.' 'Therefore the ,only mode "of securing increased lowfin the heater resides, a decrease; in its {internal resistance, whiclij must sometimes be made extremely small. 1in 'fonder-to secure ar proper v gas flow as compa redv with many .recent downwardlyturned :discharge passage which nal resistance. .Thel necessity of decreasing mulers which hi'eextremely small interthe heater resistance is also' emphasized by the ,increasing use'gof small-diameter, longstroke; high-speed 'engi-nes,l whose exhaust gases are of comparatively low tempera.

ture so thatgreat heater e-.fliciency is necessary .to secure adequate results therefrom.

By using a heater of less :internal resistance 'there being'fan inlet chamber and an outthat the muier, as'by making it of the form here shown a" maximum.. gas How is pro"-v duced; while' by properly. bi-eaklng` up. the

as v`iow and increasing 'theradiatin'g and squali-size, which I esteem Athe preferable I preferablyy cover the radiating device above described by means of a suitable 'h'ous-y ing, such as that shown at 36 in Figs. 1 3 and 4,-preferably made of perforated sheet metal and adapted to allow the free circulationo` air while keeping the riders feet and clothing outvof immediate contact with,

the heated pipes. It will be understood that many changes in detail, design and vconstruction can be madewithin the scope of my invention, wherefore I do not limitmyself except as defined in the claimshereto annexed or except as rendered necessary by the rior state of thefart. v

aving thus described my'inventiomwhat I claim is l Y v 1. In a device of thc character described, the combination :with an internal-combustion engine havingy a plurality "of exhaust pipes, of a heater having outlets and a plurality of inlets equal in number to said ex haust pipes and connected one to each of internal resistances between each of said Iinlets' and the outlet there-for, valves for f such connectlons, and ymeans for moving. l

said valves simultaneously'.
